Diagnosis of human coronavirus infections in children using enzyme-linked immunosorbent assay
Insights
A new enzyme-linked immunosorbent assay (ELISA) effectively diagnoses human coronavirus (HCV) in children. This diagnostic tool identified HCV in 28.2% of pediatric respiratory infection samples, showing its clinical utility.
Area of Science:
- Virology
- Immunology
- Pediatric Infectious Diseases
Background:
- Human coronavirus (HCV) infections are a significant cause of acute respiratory illness in children.
- Accurate and rapid diagnostic methods are crucial for managing pediatric respiratory infections.
Purpose of the Study:
- To develop and evaluate an enzyme-linked immunosorbent assay (ELISA) for the diagnosis of human coronavirus (HCV) infections in children.
- To assess the prevalence of HCV in pediatric patients with acute respiratory infections using the developed ELISA.
Main Methods:
- Collected 177 respiratory samples (nose swabs, throat swabs, nasopharyngeal aspirates) from 30 children with acute respiratory infections.
- Utilized a newly developed enzyme-linked immunosorbent assay (ELISA) to detect HCV antigens in the collected samples.
Main Results:
- The developed ELISA detected HCV antigens in 28.2% of the tested pediatric respiratory samples.
- The assay demonstrated potential for identifying HCV infections in the pediatric population.
Conclusions:
- The newly developed ELISA is a promising tool for diagnosing human coronavirus infections in children.
- Further research is warranted to validate the ELISA for broader applications, including adult infections.
Abstract:
An enzyme-linked immunosorbent assay (ELISA) was developed for diagnosing human coronavirus (HCV) infections in children. One hundred and seventy seven nose swabs, throat swabs, and nasopharyngeal aspirates were collected from 30 children suffering from acute respiratory infections. These samples were tested for HCV antigens by ELISA and 28.2% of the samples were shown to be HCV positive. These results indicate that our ELISA should prove useful in the diagnosis of HCV infections in children. Further studies are in progress to extend the ELISA to detect HCVs in experimentally and naturally acquired infections in adults.
